[SR-Users] IMC module - #join to private room crashes kamailio

Hi Daniel,

here is the backtrace:

I'm not sure if I got the right thing. I got it with gdb
/usr/local/kamailio-ozren/sbin/kamailio --core core and called bt in gdb.

I've repeated scenario described in the first mail: user tries to join in a
private room without getting an invite first.

Best regards,
Ozren
